Simutrans and Ubuntu 20.04
« on: July 18, 2020, 07:00:49 AM »
On Ubuntu 20.04, Simutrans crashes with a memory access error if it contains Midi (SDL_mixer, SDL2_mixer).

Is this an Ubuntu bug or a Simutrans bug?

I don't get a crash (I'm using 20.04, too) so I believe this must be an issue with your Ubuntu configuration. Do you have a backtrace?

no
Try the 120.4.1 Simutrans included with Ubuntu 20.04. And I use the German attitude.

or install from here https://simutrans-germany.com/wiki/wiki/en_Simutrans_repo_deb

A test with an SDL2 version without midi works.

From Debian:

Package: simutrans
Version: 121.0-1
Installed-Size: 5632
Maintainer: Debian Games Team <Pkg-games-devel@alioth-lists.debian.net>
Architecture: amd64
Depends: libbz2-1.0, libc6 (>= 2.29), libgcc-s1 (>= 3.0), libsdl2-2.0-0 (>= 2.0.10), libsdl2-mixer-2.0-0 (>= 2.0.2), libstdc++6 (>= 5.2), zlib1g (>= 1:1.1.4), simutrans-pak64 (>= 120.0.1), simutrans-data (= 121.0-1)

Whereas sdl-mixer on your Ubuntu system seems to be only 1.2. Maybe run "apt-get install libsdl2-mixer-2.0-0" and see if it fixes problem?

Seems to be a bug in SDL_mixer 1.x: Bug report for Extended. So installing SDL_mixer 2.x should indeed fix the issue.
